An unnamed State Department official who works in the Office of Information Programs and Services (IPS) is interviewed by the FBI on this day. According to a later FBI summary of the interview, she claims that around August 10, 2015, just a week before the interview, “[redacted] from Office of the Secretary of Defense (OSD) called [her] and told her Centcom records showed approximately 1,000 work-related emails between Clinton’s personal email and General David Petraeus, former commander of Centcom and former director of the CIA. Most of those 1,000 emails were not believed to be included in the 30,000 emails that IPS was reviewing. Out of the 30,000 emails, IPS only had a few emails from or related to Petraeus…” She “recommended the FBI should talk with [redacted] regarding the alleged 1,000 emails between Clinton and Petraeus.” (Federal Bureau of Investigation, 9/23/2016)

On September 25, 2015, the New York Timeswill report on the existence of 19 work-related emails between Clinton and Petraeus sent in January 2009 that were not turned over when Clinton gave what she said was all her 30,000 work-related emails to the State Department in December 2014. Since that time, neither these 19 emails nor any other of the alleged 1,000 emails between them have been made public.
